Nozzle Assembly and Method for Fluid Dispensing

ABSTRACT

A fluid delivery system for dispensing fluid can include a dispenser, such as a trigger engine-type dispenser, configured to draw fluid up from a container. A nozzle assembly can include a nozzle, and a nozzle slide. The nozzle slide can be configured to slide and/or rotate relative to the shroud to provide different dispensing modes. In alternative examples, the nozzle can be configured to rotate in 30 degree increments relative to the shroud to provide the different dispensing modes or the nozzle assembly can include a nozzle extension, and the nozzle extension can be configured to rotate relative to the shroud to provide different dispensing patterns out of the nozzle. In another example a first nozzle can be configured to provide one or more dispensing modes, and a second nozzle can be configured to provide a different dispensing mode than the first nozzle. Methods of dispensing fluids and methods of assembling fluid dispensers are also disclosed.

FIELD

The present disclosure relates generally to fluid dispensing assembliesand, more particularly, to nozzle assemblies capable of producingdifferent fluid dispensing modes.

I. BACKGROUND

Fluid dispensers can take on various general forms, e.g., triggersprayers, finger type pumps, aerosol dispensers, etc. Nozzle assembliescan be coupled to such fluid sprayers to project different fluiddispensing patterns, e.g., stream, spray (divergent or conical), aeratedfoam, and the like during dispensing. The different dispensing patternscan be selected by the user and included as indicia on the fluiddispensers as modes, such as: “OFF”, “SPRAY,” “STREAM,” etc.

The design of such fluid dispensers generally depends on the intendedapplication and/or the characteristics of the fluid that is dispensed.For example, if the fluid is intended to be suspended in the air or isintended to provide increased coverage on a surface, a nozzle assemblyto project a divergent spray may be used, but if the fluid is intendedto be applied to a localized region on a surface, e.g., carpet, wood, apainted surface, etc., a nozzle assembly to project a stream may beused. Product can be dispensed from a bottle by means of a fluiddispenser, such as a trigger engine.

FIG. 1F shows a front view of the nozzle assembly in the userselected “SPRAY” or “STREAM” mode and demonstrates the alignment ofspray channels 119 a-c, 117 b, 117 d, and 117 f. FIG. 1G depicts across-sectional view of the fluid dispenser and nozzle assembly 110 inthe “SPRAY MODE” and illustrates the fluid flow path of the fluid beingdispensed through the fluid dispenser.

FIG. 1H shows a perspective view of the fluid dispenser and nozzleassembly 110 in the user selected “STREAM” mode. FIG. 1I shows a frontview of the nozzle assembly 110 in the user selected “SPRAY” or “STREAM”mode and demonstrates the alignment of spray channels 119 a-c, 117 b,117 d, and 117 f. FIG. 1J depicts a cross-sectional view of the fluiddispenser and nozzle assembly 110 in the “SPRAY MODE” and illustratesthe fluid flow path of the fluid being dispensed through the nozzleassembly 110.

As shown in FIG. 1A, the fluid dispenser 100 can include a nozzleassembly 110, a trigger engine 20, a shroud 102, which acts as a housingfor the fluid dispenser 100, and an internally threaded cylindricalportion 30 for securing or coupling the fluid dispenser to a containeror bottle (not shown). The housing of the fluid dispenser includes aninlet portion and an outlet portion for fluid.

As shown in FIGS. 1A and 1B, the trigger engine 20 can include triggerlever 22, a pumping mechanism formed of a cylinder 24 that receives apiston and spring assembly (not shown), a dispensing tube 26, aninternal check valve (not shown), and an internal passageway 28. Thetrigger engine 20 can also include a cylindrical dip tube 40 whichextends into an opening of the container or bottle and into the fluidfor drawing the fluid up from the container and into the trigger engineand into the nozzle assembly 110.

When the user actuates the trigger lever 22, fluid is drawn up fromthrough the dip tube 40 past the check valve and into the cylinder 24.Cylinder 24 is in fluid contact with the internal passageway 28. As theuser continues to actuate the trigger lever 22, fluid is dispensed fromthe internal passageway 28 into the dispensing tube 26. The dispensingtube 26 can be connected to a nozzle assembly and fluid is thendispensed through the nozzle assembly 110 as discussed herein. Thetrigger engine 20 can be used in conjunction with any of the nozzleassemblies and configurations described herein.

As shown in FIG. 1B, the nozzle assembly 110 can include a nozzle 160, anozzle slide 112, a nozzle insert 114, a slit valve 116, and anintermediate pipe 118. The nozzle slide 112 can include the nozzle 160,which is defined by a portion that extends forward from an outer rim134. The nozzle slide 112 can include a handle 113 for sliding theintegrally connected nozzle 160 relative to the shroud 102.

The nozzle slide 112 is configured to slide in a linear manner relativeto the shroud 102 to provide different dispensing patterns out of thenozzle 160. The nozzle slide 112 is also configured to rotate relativeto the shroud to provide the closed or off position. The nozzle slide112 can be fixed to the nozzle 160 such that when the nozzle slide 112slides or rotates relative to the shroud 102, the nozzle 160 also slidesor rotates relative to the slit valve 116. The outer rim 134 of thenozzle slide 112 can be configured to limit the movement of the slidevalve 112 in the rear direction within a slot 104 located in the shroud102. Likewise, a locking tab or locking mechanism (not shown) can beincluded on the nozzle slide 112 for preventing the nozzle slide 112from moving too far forward in the slot 104 or from coming out of theslot 104 on the shroud 102.

The intermediate pipe 118 can be placed into fluid contact with thedispensing tube 26 of the trigger engine 20. In this example, a smallerdiameter portion 118 a on the intermediate pipe 118 can be provided tofit within and provide a seal between the intermediate pipe 118 and thedispensing tube 26 of the trigger engine 20. The intermediate pipe 118acts as a conduit for the fluid advanced from the dispensing tube 26from the trigger engine 20.

The intermediate pipe 118 can also provide an inner seal surface forwhen the nozzle slide 112 is slid forward in the shroud 102. Inparticular, the slit valve 116 can be located in an increased diameterportion 118 b of the intermediate pipe 118 or a front portion of theintermediate pipe 118. Alternatively, the slit valve 116 can be formedas part of the intermediate pipe 118. The slit valve 116 can stay in afixed relation to the intermediate pipe 118 and can form a seal withinthe intermediate pipe 118. In particular the slit valve 116 includes aradially extending flange 123, which seals against an interior chamberformed by the intermediate pipe 118 in the increased diameter portion118 b. Additionally, the decreased diameter portion 118 a limits themovement of the slit valve when the flange 123 abuts against thedecreased diameter portion 118 a. The slit valve 116 provides a one-wayvalve for fluid flow, as well as, provides multiple slit valve spraychannels 117 a-f. In this example, as shown in FIGS. 1D and 1F the slitvalve 116 can be provided with six slit valve spray channels 117 a-f.

The nozzle insert 114 can be pressed into or molded into the nozzle 160of the nozzle slide 112. The nozzle slide 112 and the nozzle insert 114can be arranged in a fixed relationship with each other and can rotateand slide together as an integral assembly. As shown in FIGS. 1D and 1F,the nozzle insert 114 contains nozzle insert spray channels 119 a-c thatcan be configured to be in alignment or non-alignment with the slitvalve spray channels 117 b, 117 d, 117 f to provide the off, spray, andstream dispensing modes. Also, the nozzle insert 114 is provided with anexit orifice 132 for dispensing the fluid from the trigger engine 20. Aswill be described in further detail below, the nozzle slide 112 togetherwith the nozzle insert 114 are configured to slide (forward and back)and to rotate relative to the intermediate pipe 118 to provide the userselected dispensing modes.

The shroud or housing 102 can be mounted onto the trigger engine 20. Theshroud 102 provides an interface with the user's hand, communicationwith the nozzle assembly 110 for dispensing mode selection, a mechanicalpath for the nozzle slide 112, and holds the assembly into place. Asshown in FIG. 1C, the shroud 102 also includes an elongated slot 104 forreceiving and guiding the handle 113 of the nozzle slide 112 andgenerally provides for sliding movement of the nozzle slide 112 alongthe length of the shroud 102.

The slot 104 can include a first portion 104 a which extends radiallyalong the shroud 102 and a second portion 104 b that extends axiallyalong the shroud 102. As shown, for example, in FIG. 1C, the slot 104can extend axially to the end of the shroud 102 to provide a visualeffect to the consumer to give the appearance that the nozzle 160 canextend from the shroud 102. This may entice the consumer to purchase theproduct.

The first portion 104 a can include a predetermined length to providethe handle 113 and nozzle slide 112 with 30 degrees of rotation relativeto the shroud 102. The slot 104 is sized to receive the handle 113 ofthe nozzle slide 112 therein and the slot 104 width generallycorresponds to width of the handle 113 of the nozzle slide 112.

The slot 104 can be located generally on the top of the shroud 102 alonga center line of the shroud 102. However, other positions and locationsof the slot are contemplated. The first portion 104 a of the slot 104can be located on either side of the shroud 102 depending on how thefluid dispenser is placed on the shelf and displayed to the consumer.Typically, fluid dispensers are placed on the shelf with the left sidefacing outward, so it may be desired to place the first portion 104 a onthe left side of the shroud 102. A locking tab or mechanism can beincluded next to the slot 104 on the shroud for preventing the nozzleslide 112 from moving too far in the slot or from coming out of the sloton the shroud 102. Again the nozzle slide 112 is also limited by theouter rim 134 of the nozzle slide 112.

FIGS. 1C and 1D show the fluid dispenser 100 in the off mode. The nozzleslide 112 is configured to rotate relative to the shroud 102 into theoff position. As shown in FIG. 1C, the handle 113 is located in thefirst portion 104 a of the elongated slot in a first or offset positionin the shroud 102, which causes the nozzle insert spray channels 119 a-cand the slit valve spray channels 117 a-f to be misaligned. Inparticular, because of the fixed relationship of the nozzle slide 112and the nozzle insert 114 when the nozzle slide 112 is rotated into theoffset position as shown in FIG. 1C, the nozzle insert spray channels119 a-c are also moved offset from the slit valve spray channels 117 a-fto cause misalignment of the spray channels 117 a-f, 119 a-c. In thisway, no fluid is permitted to pass from the slit valve 116 the nozzleinsert 114. FIG. 1D shows a front view of the nozzle assembly 110 in theuser selected “OFF” mode and depicts the misalignment of the nozzleinsert spray channels 119 a-c and the slit valve spray channels 117 a-f.

In the off mode as shown in FIG. 1D, the nozzle insert spray channels119 a-c and the slit valve spray channels 117 a-f are offset 30 degreesrotationally relative to each other. Consequently, the slit valve spraychannels 117 a-f do not line up with the nozzle insert spray channels119 a-c, thus, preventing any fluid from being dispensed and providingan off mode or position.

To place the fluid dispenser into a first dispensing mode, shown as thespray mode from the off mode, the user rotates the nozzle slide 112 tothe 0 degree position relative to the shroud 102 as shown in FIG. 1E. Asshown in FIG. 1E, the handle 113 is located in the second portion 104 bof the elongated slot 104 in a second position or a rearward mostposition in the second portion 104 b of the elongated slot 104. Thiscauses the nozzle insert spray channels 119 a-c and the slit valve spraychannels 117 a-f to be aligned and creates fluid contact between theslit valve 116 and the nozzle insert 114. Because of the fixedrelationship of the nozzle slide 112 and the nozzle insert 114, when thenozzle slide 112 is rotated into the second position as shown in FIG.1E, the nozzle insert spray channels 119 a-c are also moved intoalignment with the slit valve spray channels 117 a-f.

FIG. 1F shows a front view of the nozzle assembly 110 in the userselected spray mode and depicts the alignment of the nozzle insert spraychannels 119 a-c and the slit valve spray channels 117 b, 117 d, and 117f. Specifically in the spray mode or position as shown in FIG. 1F,nozzle insert spray channel 119 a aligns with slit valve spray channel117 b, nozzle insert spray channel 119 b aligns with slit valve spraychannel 117 d, and nozzle insert spray channel 119 c aligns with slitvalve spray channel 117 f, thus providing three separate channels forthe fluid to be dispensed through the nozzle insert 114.

FIG. 1G shows a side cross-sectional view of the fluid dispenser in thespray mode. FIG. 1G depicts a fluid flow path through the fluiddispenser 100. As shown in FIG. 1G, the fluid is drawn up through thedip tube 40, through the trigger engine 20, through the slit valve 116,and out through the nozzle insert 114 and finally through the exitorifice 132. FIG. 1G also demonstrates the spacing between the slitvalve 116 and the nozzle insert 114. When in the spray mode, the frontface 116 a of the slit valve 116 and an interior face 114 a of thenozzle insert 114 are configured to have a minimal spacing to maintainthe fluid swirl generated in the slit valve. In one example, a frontface 116 a of the slit valve 116 and an interior face 114 a of thenozzle insert 114 have a spacing of approximately 0.015 in. to 0.025 in.

To place the fluid dispenser into, a second dispensing mode, shown asthe stream mode from the spray mode, the user slides the nozzle slide112 to a third position within the second portion 104 b in the slot 104as shown in FIG. 1H. As shown in FIG. 1H, the handle 113 is located inthe second portion 104 b of the elongated slot 104 in a third positionslightly forward of the second position. As such, a user slides thehandle 113, and thus the nozzle slide 112 in a forward direction to movebetween a first dispensing mode and a second dispensing mode. The outerrim 134 of the nozzle slide 112 is moved out of contact with and in aspaced relation from the shroud 102 such that a front portion includingthe nozzle 160 of the nozzle slide 112 extends outward in a forwarddirection from the shroud 102.

FIG. 1I shows a front view of the nozzle assembly 110 in the userselected stream mode and depicts the alignment of the nozzle insertspray channels 119 a-c and the slit valve spray channels 117 b, 117 d,and 117 f. As illustrated in FIG. 1I, in the third position, the slitvalve 116 and the nozzle insert 114 do not change angular position withrespect to one another and the nozzle insert spray channels 119 a-c andthe slit valve spray channels 117 a-f remain aligned and fluid contactis maintained between the slit valve 116 and the nozzle insert 114.However, the spaced relationship between the nozzle insert 114 and theslit valve 116 creates a stream-like spray from the fluid dispenser 100.

FIG. 1J shows a side cross-sectional view of the fluid dispenser in thestream mode. FIG. 1J depicts a fluid flow path through the fluiddispenser 100. Similar to the second slide valve 112 position, as shownin FIG. 1J, the fluid is drawn up through the dip tube 40, through thetrigger engine 20, through the slit valve 116, out through the nozzleinsert 114, and finally through the exit orifice 132. FIG. 1J alsodemonstrates an increased spacing between the slit valve 116 and thenozzle insert 114 from the second slide valve 112 position (spray mode)to the third slide valve 112 position (stream mode).

When in the stream mode, the front face 116 a of the slit valve 116 andan interior face 114 a of the nozzle insert 114 are configured to havean increased spacing or offset from that of the spray mode. This offsetis directly related to, and determined by, the linear travel of thenozzle slide 112 that the user moves to achieve the various dispensingmodes.

In one example, in the stream mode, the front face 116 a of the slitvalve 116 and the interior face 114 a of the nozzle insert 114 can havea larger spacing ranging from 0.125 in. to 2 in. In another example, thespacing between the front face 116 a of the slit valve 116 and theinterior face 114 a of the nozzle insert 114 can range from 0.5 in. to 1in. This additional spacing allows the fluid swirl generated in the slitvalve 116 to re-converge and form a stream upon exiting the nozzleinsert exit orifice 132. Also, as shown in FIG. 1J, during the streammode, the nozzle 160 is located forward and away from the slit valve116. Locating the nozzle 160 forward (i.e., offsetting the nozzle 160from the slit valve 116) causes the swirl chamber that would otherwisebe created by the slit valve to be eliminated and fluid is dispensed asa stream.

The nozzle slide 112 does not move linearly or axially along the shroud102 between the first position (off mode) and the second position (spraymode). Rather the nozzle slide 112 only rotates relative to the shroudbetween the first position (off mode) and the second position (spraymode). The nozzle slide 112 can move linearly in a forward directionbetween (i) the second position (spray mode) in which the front tip ofthe nozzle slide 112 is approximately even with or behind a verticalplane P1 defined by the front wall of the spray bottle or container C;and (ii) the third position (stream mode) in which the front tip of thenozzle slide 112 is positioned beyond the plane defined by the frontwall of the spray bottle or container C. In this way, the nozzle 160 caninclude a tip portion 160 a and a slide portion 160 b, and the slideportion 160 b can be configured to move outward in a substantiallylinear manner relative the housing or shroud 102 for moving the tipportion 160 b beyond the vertical plane defined by the front wall of thecontainer.

FIGS. 2A and 2B illustrate another example of a fluid dispenser 200 witha nozzle slide 212 configured to dispense product from a container. Theexample of FIGS. 2A and 2B is similar to the example of FIGS. 1A-J wherelike reference numerals represent like components. The nozzle assembly210 can be placed onto a similar trigger engine 20 as the embodimentdepicted in FIGS. 1A-1J. However, in the example depicted in FIGS. 2Aand 2B, the nozzle slide 212 does not rotate in relation to the fluiddispenser, rather the nozzle slide 212 is only permitted to move axiallyor linearly in relation to the slit valve (not shown) to create twodifferent spray patterns. In this example, the nozzle insert is omitted.Additionally, a nozzle adapter 236 can be provided instead of anintermediate pipe to provide a channel for the fluid from the triggerengine to the nozzle assembly.

In this example, the nozzle slide 212 can be configured to move into twoseparate positions to provide spray and stream modes. In particular, thenozzle slide 212 is configured to move to a first position in arearward-most position to provide a spray pattern and a second positionrelative to the shroud to provide a stream pattern. In alternativeexamples, the nozzle 260 can be provided with an off mode when thenozzle slide 212 is in the rearward-most position on a shroud. In suchan example, the nozzle 260 may combine the off mode with only onedispensing mode or with more than one dispensing mode.

As shown in FIG. 2A, the example nozzle assembly 210 generally includesa nozzle 260, a nozzle slide 212, a nozzle adapter 236, and a slit valve(not shown). The nozzle slide 212 can include a handle 213, which can begrasped by the user to adjust the nozzle slide 212 relative to the fluiddispenser 200. The nozzle adapter 236 can include multiple slit valvespray channels 221. The nozzle adapter 236 is configured to receivefluid from a trigger engine, which can be the same trigger engine typeas described above, and directs the fluid into the slit valve. Thenozzle adapter 236 also permits the attachment of the nozzle slide 212to the trigger engine. The slit valve (not depicted) can be formed aspart of the nozzle adapter 236.

FIG. 2A shows the nozzle slide 212 in the first position or retractedposition. In the first position or the retracted position the nozzle 260is located at a first distance away from the slit valve to provide thespray mode. FIG. 2B shows the nozzle slide in an extended position. Asshown in FIG. 2B in the second position the nozzle 260 is located at asecond distance away from the slit valve to provide the stream mode. Thesecond distance is greater than the first distance to provide the streammode.

To move the nozzle slide 212 to the retracted position, the user cangrasp the handle 213 connected to the nozzle slide 212 and move thenozzle slide 212 to the rearward most position on the fluid dispenser.When in the retracted position, the fluid dispenser 200 will produce aspray pattern or a wider spray pattern. When in the spray mode, theinner face 260 a of the nozzle 260 and an outer face of the slit valveare configured to have a minimal spacing to maintain the fluid swirlgenerated in the slit valve and to dispense a spray out of the nozzleexit orifice 232 of the nozzle 260.

To move the nozzle slide 212 to the extended position, the user cangrasp the handle 213 connected to the nozzle slide 212 and move thenozzle slide 212 to the forward most position on the fluid dispenser.When the extended mode, the dispenser will produce a stream pattern.When in the stream mode, the inner face 260 a of the nozzle 260 and anouter face of the slit valve are configured to have an increased spacingfrom that of the spray mode to produce a stream spray pattern. Thisadditional spacing allows the fluid swirl generated in the slit valve tore-converge and form a stream upon exiting the nozzle exit orifice 232.

In the above nozzle slide examples described in relation to FIGS. 2A,and 2B, the nozzle slide 212 can move linearly in a forward directionbetween (i) a first position in which the front tip of the nozzle 260 isapproximately even with or behind a plane defined by the front wall ofthe spray bottle; and (ii) a second position in which the front tip ofthe nozzle 260 is positioned beyond the plane defined by the front wallof the spray bottle. The first position may be achieved when the nozzle260 is in the off position, and/or the first dispensing mode, such asspray mode, while the second position may be achieved when the nozzle isin the second dispensing mode (e.g., the stream mode).

FIGS. 3A and 3B depict another example shroud and nozzle assembly. Thisexample is similar to the examples of FIGS. 1A-J, 2A-2B and can includethe same internal working components with the same functionality as theexample described in relation to FIGS. 2A-2B. Additionally, likereference numerals represent like components and the example nozzleassembly can be placed onto a similar trigger engine as the exampleshown and described in relation to FIGS. 1A-1J.

In this example, the shroud 302 can include icons to indicate dispensingmode, and the nozzle slide can include a refined geometry to provide amore aesthetically desirable fluid dispenser 300. The icons can includeoff 350, spray 352, and stream 354 modes. The nozzle slide 312 caninclude an outwardly extending tab 313, which can be grasped by the userto toggle the nozzle slide 312 to the different modes. The nozzle slide312 can be moved to a first, second, and third position to producedifferent dispensing modes.

FIG. 3A depicts the fluid dispenser 300 in the first position or an offposition where the internal components can be positioned in closedrelation to each other as described above. FIG. 3B depicts the fluiddispenser in a second position or a spray position where the internalcomponents can be positioned in an open relation to each other asdescribed above to produce a spray pattern. The fluid dispenser 300 canalso have a third position or a stream mode in which the internalcomponents can be positioned in an open relation to each other asdescribed above to produce a stream pattern.

FIGS. 4A-4C depict another nozzle assembly example where a nozzle slide412 can be configured to be moved linearly by the user. This example isalso similar to the examples of FIGS. 1A-J, 2A-2B and can include thesame internal working components with the same functionality as theexample described in relation to FIGS. 2A-2B. Like reference numeralsrepresent like components and the example nozzle slide assembly can beplaced onto a similar trigger engine as the example shown and describedabove in relation to FIGS. 1A-1J.

In this example, the rear portion of the shroud 402 can include icons toindicate the dispensing mode to the user. The icons can include off 450,spray 452, and stream 454 modes. Like in the examples shown in describedin relation to FIGS. 3A-3B, the linear sliding of the nozzle slide 412of the nozzle assembly 410 produces a stream mode 454 when the nozzleslide 412 is fully extended, a spray mode 452 in the middle position,and an off mode 450 when the nozzle 460 is fully retracted in the shroud402. In this example, the handle 413 can be located in a rearwardlocation on the shroud 402. Because of the rearward location of thehandle 413, the user is able to switch between dispensing modes with asingle handed operation, by flipping their thumb.

FIG. 5 depicts another nozzle slide assembly example where a nozzleslide 512 can be configured to be moved linearly by the user. Thisexample is also similar to the examples of FIGS. 1A-J, 2A-2B and caninclude the same internal working components with the same functionalityas the example described in relation to FIGS. 1A-J, 2A-2B. Likereference numerals represent like components, and the example nozzleassembly 510 can be placed onto a similar trigger engine 20 as theexample shown and described above in relation to FIGS. 1A-1J.

In this example, the nozzle slide 512 can be configured to convert thelinear motion of the movement of the nozzle slide 512 to a rotary motionof the nozzle 560 to switch between dispensing modes. The middle portionof the shroud 502 can include icons to indicate the dispensing mode tothe user. The icons can include off 550, spray 552, and stream 554modes. The nozzle slide 512 can be adjusted linearly by grasping thehandle 513 to move the nozzle slide 512 in relation to the fluiddispenser.

In the above nozzle slide examples, when the nozzle slides areselectively adjusted between the first dispensing mode (e.g., the spraymode) and the second dispensing mode (e.g., the stream mode), the nozzleis extended in an outward direction relative to the trigger housing orshroud. The extension of the nozzle may allow a user to better reachinto tight crevasses (e.g., corners).

In the above nozzle slide examples, it may be desired to limit the fronttip of the nozzle from extending past the plane defined by the frontwall of the spray bottle during manufacturing and/or packaging. Forexample, as shown in FIG. 1G, the front of the nozzle 160 can define aplane P1, which does not extend past a plane defined by a front wall ofa spray bottle (not shown). The arrangement allows for a shrink sleeve162 to be applied to the bottle after the trigger is installed, and theshrink sleeve 162 can be applied from the top. Therefore, it may bedesirable to limit the front tip 160 a of the nozzle 160 from extendingpast the plane defined by the front wall of the spray bottle. Inaddition, in certain scenarios the finished bottles may be dropped intoboxes for shipment and this may require that the bottle (as opposed tothe trigger) to define the outermost periphery of the final product.However, during use the nozzle can extend past the plane defined by thefront wall of the spray bottle. For example, as shown in FIG. 1J, thefront of the nozzle 160 defines a vertical second plane P2, which canextend past the front wall of a spray bottle.

FIGS. 6A-6D depict another example shroud 602 and nozzle assembly 610where the nozzle 660 rotates to provide the desired spray pattern. Thisexample is also similar to the examples of FIGS. 1A-J, 2A-2B and caninclude the same internal working components with the same functionalityas the example described in relation to FIGS. 1A-J, 2A-2B. However, theexample of FIGS. 6A-6D does not include a nozzle slide. Rather thenozzle 660 only rotates relative to the shroud 602 to provide thedesired dispensing modes. Like reference numerals represent likecomponents and the example shroud 602 and nozzle assembly 610 can beplaced onto a similar trigger engine as shown and described above inrelation to FIGS. 1A-1J.

As shown in FIGS. 6A-6D, an outwardly extending tab 613 located on thenozzle 660 provides a grasping portion for the user to select thedesired dispensing mode. To switch between dispensing modes requires 30degrees of total rotational movement to make it easier for the user toselect between modes than for example a 90 degree rotational movement.The 30 degree movement is achieved using the same slit valveconfiguration shown and described in relation to the examples above, andthe nozzle 660 can be stopped at intermediate positions relative to theslit valve to achieve the desired dispensing modes. Additionally, otherrotational increments are contemplated to achieve the desired dispensingmodes, including rotational increments less than 90 degrees.

As shown in FIGS. 6B-6C, indicia are formed (e.g., molded) onto theshroud 602 and can be configured to align with the tab 613 to select thedesired dispensing mode of the nozzle 660 to identify the various modesfor the user. It is also contemplated that the indicia could be placedon other locations of the shroud and dispenser such as the triggerengine. The icons can include off 650, spray 652, and stream 654 modes.FIG. 6B shows the fluid dispenser in the stream mode. FIG. 6C shows thefluid dispenser in the off mode. FIG. 6D shows the fluid dispenser inthe spray mode.

FIG. 7 depicts another example shroud 702 and nozzle assembly 710 thatalso has a rotating nozzle 760 that rotates to provide the desired spraypattern. The example depicted in FIG. 7 is similar to the example shownand described in relation to FIGS. 6A-6D, however, this example includesa refined shroud 702 and nozzle 760 geometry which takes intoconsideration the molding and assembly of the parts. This example isalso similar to and can include the same internal working componentswith the same functionality as the example described in relation toFIGS. 1A-J, 2A-2B. However, the example of FIG. 7 also does not includea nozzle slide. Like reference numerals represent like components andthe example shroud 702 and nozzle assembly 710 can be used with asimilar trigger engine as the example shown and described above inrelation to FIGS. 1A-1J.

In the example shown in FIG. 7, to switch between dispensing modesrequires 30 degrees of total rotational movement to make it easier forthe user to select between modes. However, other rotational incrementsare contemplated. The 30 degree movement is achieved using the same slitvalve shown and described in relation to the examples above. The nozzle760 can be stopped at intermediate positions relative to the internalslit valve to achieve the desired dispensing modes.

As shown in FIG. 7, an outwardly extending tab 713 located on the nozzle760 provides a grasping portion to select the desired dispensing mode.Indicia can be formed (e.g., molded) onto the shroud 702 and can beconfigured to align with the tab 713 to select the desired dispensingmode of the nozzle 760 the nozzle 760 and/or the trigger housing/shroudto identify the various modes for the user. The icons can include “OFF”750, “ON” 752, and other dispensing modes. FIG. 7 shows the nozzle 760in an off mode.

FIGS. 8A-8C depict an example of a flip-type nozzle assembly 810. Theexample depicted in FIGS. 8A-8C is also similar to the examples of FIGS.1A-J, 2A-2B and can include the same internal working components withthe same functionality as the example described in relation to FIGS.1A-J, 2A-2B. Like reference numerals represent like components and theexample shroud 802 and nozzle assembly 810 can be used in conjunctionwith a similar trigger engine as the example shown and described abovein relation to FIGS. 1A-1J.

The example of FIG. 8A-8C does not include a nozzle slide. Instead, thenozzle assembly 810 includes a nozzle extension 862, which is configuredto rotate on a pivot 864 on the nozzle 860. The nozzle extension 862 canbe a tube and can be provided with two flow channels for differentdispensing modes. The rotation of the nozzle extension 862 provides thedifferent dispensing modes for the nozzle assembly 810. FIGS. 8A and 8Cdepict the nozzle assembly in the spray mode, and FIG. 8B depicts thenozzle assembly in the stream mode. Also as shown in FIGS. 8A-8C, thisexample can include two exit orifices 832 a and 832 b.

The nozzle assembly 810 operates in a similar fashion as the nozzleslide embodiments by providing an increased length passageway betweenthe slit valve (not shown) and the exit orifices 832 a and 832 b. Thenozzle extension 862 can include a first internal passageway thatextends in a radial direction in the tube and a second internalpassageway that extends in an axial direction along the tube. The firstpassageway is connected to the first exit orifice 832 a and the secondpassageway is connected to the second exit orifice 832 b.

When the nozzle extension 862 is in the down position as in FIGS. 8A and8C, the fluid will travel a shorter distance through the first internalpassageway between the exit orifice 832 a and the internal slit valve toprovide a spray mode. The exit orifice 832 a can also be configured todispense a spray from the nozzle 860. When the nozzle extension 862 isin the up position as shown in FIG. 8B, the fluid will travel throughthe second passageway, a longer distance between the exit orifice 832 band the internal slit valve, to provide a stream mode or bead-likeapplication of chemistry when the trigger is pulled.

In one example, when the nozzle extension 862 is in the raised position,the exit orifice 832 a and the first passageway is blocked by a wallformed by the nozzle 860 such that no fluid is dispensed from the exitorifice 832 a when the nozzle is in stream mode. Additionally, the firstpassageway can provide a seal on the nozzle 860 to prevent fluid fromtraveling out of the nozzle 860 through the second passageway. Thenozzle extension 862 when in the up or the extended position providesextra reach for the user. For example, the user can reach into tightedges or corners, and apply chemistry to a specific location.

FIGS. 9A-9I depict another example of a fluid dispenser 900 configuredto draw up fluid from a container and to provide various dispensingmodes. FIGS. 9A-9C illustrate the components that form the fluiddispenser 900. In particular, FIG. 9A shows an isometric view of apartial assembly of the example fluid dispenser 900 with the slidingnozzle 912 in a first closed position, and FIG. 9B shows an isometricview of a partial assembly of the example fluid dispenser 900 with thesliding nozzle 912 in a second opened position. FIG. 9C shows anisometric, exploded view of the fluid dispenser 900.

In this example, the fluid dispenser 900 nozzle assembly 910 can includea first nozzle or rotary nozzle 960, and a second nozzle or slidingnozzle 912, both of which are configured to dispense product indifferent dispensing modes. In this example, the rotary nozzle 960 canbe configured to provide “SPRAY,” “OFF,” and “STREAM” modes, and thesliding nozzle 912 can be configured to dispense a bead-like stream ofproduct from the fluid dispenser 900.

The nozzle assembly may include a nozzle adapter 918 that can beconfigured to fit onto a trigger engine 20 to modify the dispensingcharacteristics of the trigger engine. The nozzle adapter 918 canprovide an interface between the first rotary nozzle 960, the secondsliding nozzle 912 and the trigger engine 20 to deliver fluid from thetrigger engine 20 to both the rotary nozzle 960 and the sliding nozzle912. The nozzle adapter 918 can also be configured to receive a slitvalve 916, which can help provide the desired dispensing characteristicsof the rotary nozzle 960.

As shown in relation to FIGS. 9A-9C, like the example described inrelation to FIGS. 1A-1J above, the fluid dispenser 900 can also includea trigger engine 20, and a shroud 902, which acts as a covering for thenozzle assembly 910 and the trigger engine 20 of the fluid dispenser900. The fluid dispenser 900 can also include an internally threadedcylindrical portion 30 for securing the fluid dispenser 900 to acontainer or bottle (not shown). The trigger engine 20 can also includetrigger lever 22, a pumping mechanism formed of a cylinder 24 thatreceives a piston and spring assembly (not shown), a dispensing tube 26,an internal check valve (not shown), and an internal passageway 28. Thetrigger engine 20 can also include a cylindrical dip tube 40 whichextends into an opening of the container or bottle and into the fluidfor drawing the fluid up from the container and into the trigger engine20 and into the nozzle assembly 910.

The rotary nozzle 960 can include a first orifice 932 a for dispensingthe fluid from the trigger engine 20 and can be configured to bemanually adjusted by the user to provide either “SPRAY,” “OFF,” or“STREAM” modes. In one example, the rotary nozzle 960 can fit onto thenozzle adapter 918 using a barb-type connection. In particular, as shownin FIG. 9D, the rotary nozzle 960 can include a recess 949 for receivinga corresponding barb 931 on an external spout 929 of the nozzle adapter918. However, other types of mechanical connections are contemplated,e.g., interference fit, threads, bayonet, ball and socket, etc., toconnect the rotary nozzle 960 to the nozzle adapter 918.

In one example, the rotary nozzle 960 can be provided with one or moreshoulders 961 around the periphery of the rotary nozzle 960 thatcorrespond with the various spray positions. Although not shown, theseshoulders can be raised slightly so that the sliding nozzle 912 will beprevented from sliding outward into the opened position by the one ormore raised shoulders if the user attempts to extend the sliding nozzle912 while the rotary nozzle 960 is in either a “STREAM” or “SPRAY”position, for example. Thus, in this example, to activate the slidingnozzle 912, a user would first have to rotate the rotary nozzle 960 tothe “OFF” or closed position before being able to extend the slidingnozzle 912 forward into the open position.

The rotary nozzle 960 can have four sides and each side can have words,abbreviations, symbols, or other indicia placed on it, such as “SPRAY,”“STREAM,” or “OFF.” In one example, the rotary nozzle 960 can bepivotally attached to the nozzle adapter 918 and allows for a user toselect between the different modes. The rotary nozzle 960 itself can beconfigured or components can be added to provide suitable dispensingcharacteristics and can include spray, stream, adjustable nozzles whichprovide for a stream of the substance to be dispensed, e.g., a nozzlewith straight channels inside the nozzle to produce a high velocitynarrow stream. For spray or mist characteristics, the rotary nozzle 960may be adapted by having, for example, suitable grooves in a spiral toimpart spin and turbulence. The rotary nozzle 960 can be configured toproduce a plume or cloud of the product to be dispensed in fine, mediumand coarse characteristics. In another example, the rotary nozzle 960may comprise an “infinity” spray-to-stream adjustable nozzle. This typeof adjustable nozzle can be a screw-type nozzle with a full range ofstream and spray patterns. Although not shown, the rotary nozzle 960 caninclude a snap fit, removable cap to allow rinsing or cleaning of thecap and/or the rotary nozzle 960.

It is also contemplated that the rotary nozzle 960 may be available in aspray only configuration, or it could be available in a foaming nozzlearrangement, wherein air intakes allow air to be introduced into thestream of material passing through the nozzle 960 either in a stream orspray pattern. This air introduction creates turbulence to mix air andthe fluid to be dispensed for foaming action.

The sliding nozzle 912 is configured to slide from a closed positionshown in FIGS. 9A and 9D to an open position as shown in FIGS. 9B and 9Eto provide bead-like stream of product from the fluid dispenser 900. Asshown in FIG. 9B and 9C, the sliding nozzle 912 can be placed on thetrigger engine 20 and can be configured to slide within the shroud 902along the trigger engine 20 and on the top of the nozzle adapter 918.

The sliding nozzle 912 can be configured to both dispense and blockfluid in the second passageway 923 b of the nozzle adapter 918. As shownin FIG. 9D, the sliding nozzle 912 is configured to block flow from theconical valve 933 when the sliding nozzle 912 is in the closed position,and as shown in FIG. 9E, the sliding nozzle 912 is configured toselectively receive product flow from the second passageway 923 b into asliding nozzle passageway 947 when the sliding nozzle 912 is in theopened position.

As shown in FIGS. 9E and 9H, the nozzle passageway 947 extends from abottom portion of the sliding nozzle 912 and forms a 90 degree bend toprovide fluid communication from a bottom portion inlet 921 of thesliding nozzle passageway 947, through the body of the sliding nozzle912. The sliding nozzle passageway 947 also routes fluid to a secondorifice 932 b in the sliding nozzle 912, which in one example can beconfigured to dispense the fluid in a bead-like stream of product.

Also as shown in FIG. 9H, The sliding nozzle 912 can be provided with around projection 943 that is configured to align with the enlargeddiameter portion 945 located on the nozzle adapter 918. The slidingnozzle 912 projection 943 can be formed larger than the enlargeddiameter portion 945 such that when the projection 943 is aligned withthe enlarged diameter portion 945 of the nozzle adapter 918, the slidingnozzle 912 locks into the nozzle adapter 918 via a friction-fit typeconnection. The projection 943 and the enlarged diameter portion 945 ofthe nozzle adapter 918 together limit the movement of the sliding nozzle912 on the fluid dispenser 900 and provide the user with a tactileresponse such that the user can feel when the sliding nozzle 912 is inthe dispensing mode. It is contemplated that the projection 945 can takeon other forms and shapes to limit the movement of the sliding nozzle912 in the open position. It is also contemplated that the nozzleadapter 918 can be configured to secure the sliding nozzle 912 in theclosed position.

As shown in FIGS. 9F-91, the sliding nozzle 912 can be provided withrails 953 which can be located in corresponding channels 955 in thenozzle adapter 918. The rails 953 and corresponding channels 955 can beoriented parallel to the sliding movement of the sliding nozzle 912. Therails 953 and corresponding channels 955 limit the movement of thesliding nozzle 912 on the fluid dispenser and ensure that the slidingnozzle 912 can only move along the top of the fluid dispenser 900 andprevent the sliding nozzle 912 from being inadvertently detached fromthe fluid dispenser 900. The rails 953 and corresponding channels 955may also provide a smooth operation of the sliding nozzle from theclosed position to the open position.

Other methods of limiting the sliding nozzle 912 in fluid dispenser 900are contemplated.

For example, forming the ends of the sliding nozzle 912 larger than theguide 927 of the nozzle adapter 918 can limit the movement of thesliding nozzle 912 in the open or closed positions. Alternatively or inaddition, the fluid dispenser 900 can also be provided with a recess toreceive the projection 943 of the sliding nozzle 912 to secure thesliding nozzle 912 in the closed position. Alternatively or in addition,the shroud 902 can be configured to frictionally engage the slidingnozzle 912 to lock the sliding nozzle 912 into place in the open orclosed position.

As shown in FIG. 9I, the sliding nozzle 912 can include one or moregripping elements 941 on the rear portion of the sliding nozzle 912 toassist the user to grasp and slide the sliding nozzle 912 to theoperating position and back to the closed position. It is alsocontemplated that the gripping elements 941 can be provided along otherportions and/or along the entire length of the sliding nozzle 912.

The nozzle adapter 918 acts as a common interface between the triggerengine 20, the sliding nozzle 912, and the rotary nozzle 960. Inparticular, the nozzle adapter 918 has one side sized to receive anoutlet of the dispensing tube 26 of the trigger engine 20, a second sidesized to receive the rotary nozzle 960, and a third side configured tobe in fluid communication with the passageway 947 on the sliding nozzle912 when the slide is moved to an extended position. The nozzle adapter918 can be placed in fluid communication with the dispensing tube 26 andcan be configured to deliver fluid to either the sliding nozzle 912 orthe rotary nozzle 960 such that the sliding nozzle 912 and the rotarynozzle 960 can modify the dispensing modes of the trigger engine 20. Thenozzle adapter 918 also helps guide the sliding nozzle 912 as thesliding nozzle 912 is moved from an open position to a closed positionand receives the rotary nozzle 960 and the slit valve 916.

As shown in FIGS. 9D and 9E, the nozzle adapter 918 can be provided witha passageway 923 which can diverge into a first passageway 923 a and asecond passageway 923 b within the nozzle adapter 918. The firstpassageway 923 a can be provided to selectively deliver fluid to therotary nozzle 960, and the second passageway 923 b can be provided toselectively deliver fluid to the sliding nozzle 912.

In addition, a conical valve 933 can be placed within an enlargeddiameter portion or recess 945 in the second passageway 923 b to directfluid flow toward the sliding nozzle 912. The conical valve 933 preventsair from traveling back into the system after the trigger lever 22 hasbeen actuated and released. The conical valve 933 can be a one-way flapvalve that allows the liquid to pass through it, but prevents air orliquid from passing back into the trigger engine 20. The conical valve933 can take on alternate configurations to route the fluid into thesliding nozzle 912 and can also be formed integral with the slidingnozzle 912 or the nozzle adapter 918.

As shown in FIGS. 9C-9E, a gasket in the form of an o-ring 925 can beplaced between the nozzle adapter 918 and the sliding nozzle 912 toprovide a seal between the second passageway 923 b in the nozzle adapter918 and the sliding nozzle passageway 947 in the sliding nozzle 912 toreduce leakage in the fluid dispenser 900. The o-ring 925 can also beplaced in the enlarged diameter portion 945 in the second passageway 923b of the nozzle adapter 918 and onto the conical valve 933. The o-ring925, thus, provides a seal between the conical valve 933 and the slidingnozzle 912.

Also while the o-ring 925 and the conical valve 933 are shown as twoseparate components, it is contemplated that the o-ring 925 and conicalvalve 933 can be integrally formed as a single component. It is alsocontemplated that a gasket could be formed integral with either thesliding nozzle 912 or the nozzle adapter 918 to provide an adequate sealbetween the sliding nozzle 912 and the nozzle adapter 918.

As shown in FIG. 9F, the nozzle adapter 918 is provided with a guide 927and channels 955 that are configured to receive the sliding nozzle 912and corresponding rails 953 therein and provide a track for the slidingnozzle 912 when the sliding nozzle 912 is moved from the closed positionto the open position. Also the enlarged diameter portion or recess 945of the nozzle adapter 918 can be provided for accommodating thecorresponding projection 943 on the sliding nozzle 912. As shown in FIG.9F, the enlarged diameter portion 945 can open into the secondpassageway 923 b and can extend through the guide 927 formed in the topof the nozzle adapter 918.

Also as shown in FIG. 9F, the nozzle adapter 918 is also provided withan external spout 929.

The outer cylindrical surface of the spout 929 of the adapter 918 can beprovided with a barb 931, which can extend circumferentially around amiddle region of the external spout 929 and can be used to secure therotary nozzle 960 in place on the nozzle adapter 918. In particular, therotary nozzle 960 corresponding barb recess 949 can receive the barb 931of the external spout 929 to secure the rotary nozzle 960 to the nozzleadapter 918. An inner cylindrical surface defining the first passageway923 a located in the external spout 929 can be configured to receive andhold the slit valve 916 therein.

As shown in FIG. 9G, the nozzle adapter 918 can also be provided withcutout portion 935 for accommodating the dispensing tube 26 of thetrigger engine 20. The nozzle adapter 918 can also be provided with aninternal spout 937 located in the cutout portion 935 of the nozzleadapter that provides for fluid communication with the dispensing tube26 and defines the nozzle adapter 918 passageway 923. The internal spout937 can either fit within the dispensing tube 26 or over an outercylindrical surface of the dispensing tube 26. As shown in FIG. 9G, theinternal spout 937 bore may also include a square keyway 939 foraligning the nozzle adapter 918 on the dispensing tube 26 to ensure thatthe nozzle adapter 918 is in the proper location during assembly. Thekeyway 939 also can prevent the nozzle adapter 918 from rotatingrelative to the dispensing tube 26 and the trigger engine 20 during use.Additionally, as shown in FIG. 9C, the dispensing tube 26 can also beprovided with a barb 951 to provide a frictional-type fit between thedispensing tube 29 and the internal spout 937 of the nozzle adapter 918.Additionally, although not required, the nozzle adapter can also in oneexample include a corresponding recess to receive the barb 951. Othermechanical connections between dispensing tube 29 and the nozzle adapter918 are also contemplated, e.g., interference fit, threads, bayonet,ball and socket, etc.

A slit valve 916 can be placed in the nozzle adapter 918 and within therotary nozzle 960 to provide the desired spray characteristics of thefluid dispenser 900. For example, the slit valve 916 can stay in a fixedrelation to the nozzle adapter 918 and can form a seal within the nozzleadapter 918. Like the slit valve 116 discussed above, the slit valve 916can also include a radially extending flange that seals against aninterior chamber formed in the nozzle adapter 918. The slit valve 916can provide a one-way valve for fluid flow and may provide multiple slitvalve spray channels depending on the desired spray characteristics. Itis also contemplated that the slit valve 916 could be formed integralwith the nozzle adapter 918 or rotary nozzle 960 to provide the desireddispensing characteristics.

The trigger engine 20 can operate in a similar fashion as discussedabove in relation to the example shown in FIGS. 1A-1J above anddispenses fluid by actuating the trigger lever 22 when either the rotarynozzle 960 or the sliding nozzle 912 are in opened positions. The usercan manipulate the rotary nozzle 960 and the sliding nozzle 912 into aplurality of dispensing modes and an off mode.

FIG. 9D shows a cross-sectional view of the fluid dispenser nozzleassembly 910 with the rotary nozzle 960 in the opened position and thesliding nozzle 912 in the closed position and illustrates the fluid flowA through the fluid dispenser 900 and the rotary nozzle 960 andillustrates the “SPRAY” and “STREAM” modes. The user can rotate therotary nozzle 960 to select the modes of the fluid dispenser 900. In oneexample, to select a stream-type application (i.e., the fluid flow fromthe nozzle 960 is a strong, generally coherent stream), the nozzle 960is pivoted until a side of the nozzle 960 with the word or indicia“STREAM” is facing upwards. Similarly, to select a spray-typeapplication (i.e., the fluid flow from the nozzle 960 is a generallyfine mist), the nozzle 960 is pivoted until a side of the nozzle 960with the word or indicia “SPRAY” is facing upwards. In examplesincluding an “off” setting, when the nozzle 960 is pivoted until a sideof the nozzle 960 with the word or indicia “OFF” is facing upwards, thenozzle 960 will be shut off and no flow will be able to emit from thenozzle 960.

When the dispensing modes of the rotary nozzle 960 are selected, therotary nozzle 960 can be configured to prevent the sliding nozzle 912from moving into the opened position. This prevents fluid from beingdispensed out of the sliding nozzle 912 when the rotary nozzle 960 is ina dispensing mode. Thus, product can only be dispensed from the slidingnozzle 912 when the rotary nozzle 960 is in the off position.

As shown in FIG. 9D, when the sliding nozzle 912 is in the retracted orclosed position, the fluid dispenser 900 can only dispense product fromthe rotary nozzle 960. This is achieved by blocking the secondpassageway 923 b in the nozzle adapter 918 with an underside surface ofthe sliding nozzle 912 when the sliding nozzle 912 is located in theclosed position. As shown in FIG. 9D, when the second passageway 923 bis blocked by the sliding nozzle 912, all the fluid is pumped throughthe first passageway 923 a in the nozzle adapter 918, the slit valve 916and to the first orifice 932 a in the rotary nozzle 960.

FIG. 9E shows a cross-sectional view of the fluid dispenser nozzleassembly 910 with the sliding nozzle 912 in the opened position andillustrates the fluid flow B through the fluid dispenser 900 and thesliding nozzle 912 to provide a bead-like stream of product. When theuser places the sliding nozzle 912 into the open extended position, thefluid dispenser 900 will dispense product from the second orifice 932 bof the sliding nozzle 912. Fluid flow from the sliding nozzle 912 isachieved by the second passageway 932 b in the nozzle adapter 918 beingin line with the internal passageway 947 in the underside of slidingnozzle 912.

As shown in relation to FIG. 9E, fluid restriction in the sliding nozzle912 passageway 947 can be less than the typical fluid path in the rotarynozzle 960 (even with the rotary nozzle 960 being left in a dispensingposition); therefore, the fluid only travels through the sliding nozzle912. Like in the above nozzle slide examples, when the sliding nozzle isin the open extended position, the extension of the nozzle may allow auser to better reach into tight crevasses (e.g., corners). However, inthis example the sliding nozzle 912 may achieve additional linearextension to achieve an extended reach for the user into these areas.

It may be desired in certain instances to prevent the fluid fromtraveling through the rotary nozzle 960 when the sliding nozzle 912 isin an opened position. In one example, as discussed above, the rotarynozzle 960 must be in the “off” setting before the user can slide thesliding nozzle 912 to the open position. Rotating the rotary nozzle 960to the closed or off position will ensure that all of the fluid will bedirected into the sliding nozzle 912, and may avoid any leakage that mayotherwise occur through the rotary nozzle 960 if the rotary nozzle 960is left in the dispensing positions, e.g. “SPRAY” or “STREAM.”Therefore, in this example, the fluid dispenser 900 is configured toonly dispense fluid from the sliding nozzle 912 while the sliding nozzle912 is in the extended or open position.

When the rotary nozzle 960 is moved into the closed or off position andthe sliding nozzle 912 is located in the closed position, fluid cannotbe dispensed from the trigger engine 20. When the sliding nozzle 912 isin the retracted position and the rotary nozzle 960 is in the “Off”position, the fluid dispenser 900 is ready for shipping and storage.

The nozzle assembly examples above are not limited to the specific spraypatterns discussed herein and any desired spray pattern can be achieveddepending on the configuration of the spray channels, slit valve, andnozzle. Additionally, any of the examples discussed herein could beadapted to accommodate attachments, working ends or tools for specificpurposes, e.g., scrubbing, polishing, disinfecting, etc.
